Abstract: A header for a high-pressure heat exchanger includes a first high-pressure transition section with inlets for multiple first high-pressure flow channels that are spaced from one another in a radial direction and collectively arranged in a substantially circular shape. The inlets for the multiple first high-pressure flow channels on a radially outer edge of the first high-pressure transition section are spaced further apart in a circumferential direction from adjacent inlets of the multiple first high-pressure flow channels than radially inward inlets are spaced from adjacent radially inward inlets of the multiple first high-pressure flow channels. The header also includes multiple first high-pressure flow channels extending from the first high-pressure transition section to a second-high pressure transition section that is configured to divide each of the multiple first high-pressure flow channels into at least two first high-pressure sub-flow channels.

Abstract: In accordance with at least one aspect of this disclosure, a transition structure for a heat exchanger can include a body defining a dome cavity. The dome cavity can be configured to transition flow between at least one first channel and a plurality of second channels having a different number than the at least one first channel.

Abstract: A ram air fan inlet assembly for cabin air compressor (CAC) motor cooling flow enhancement includes a gas path defined by a ram air duct and a fan section, a CAC motor cooling return duct having an outlet provided through a wall of the ram air duct, and a centerbody body disposed in the ram air duct. The fan section is disposed immediately downstream and abutting the ram air duct. The ram air duct and fan section share a common axis. The centerbody is disposed about the common axis and configured to reduce of volume of the gas flow path in the ram air duct. The centerbody and the outlet axially overlap.

Abstract: A heat exchanger includes a plurality of longitudinally-extending first channels and a plurality of second channels fluidly isolated from the plurality of first channels. Each first channels includes a plurality of spiraling internal fins and a plurality of external fins. The internal fins extend from and are integrally formed with the internal walls of the first channel. The external fins connect extend from and are integrally formed with the external walls of the first channels, connecting channels together. The plurality of second channels is defined in part by external walls of the plurality of first channels and the plurality of external fins.

Abstract: A heat sink with a primary flow volume, an inlet, an outlet, a bottom plate, a top plate, distribution, heat transfer and collector sections, and flow paths between pillars. The inlet cross-section defines the primary flow volume cross-section and the length of the primary flow volume extends into the heat sink at a right angle to the inlet cross-section. The distribution section is proximate to the flow inlet and has distribution pillars extending from the bottom or top plate. The heat transfer section is proximate to the distribution section and has heat transfer pillars extending from the bottom or top plate. The collector section is proximate to the heat transfer section and has collector pillars extending from the bottom or top plate. The distribution cross-section is greater than the heat transfer cross-section which is smaller than the collector cross-section. The flow paths extend outside of the primary flow volume.

Abstract: A heat exchanger having: front and aft ends; heat exchanger cores in an annular loop that define circumferential gaps between adjacent pairs of the cores, the cores, individually or as axially aligned sets, extend from the front to aft ends and have facing inlet sides and circumferentially facing outlet sides configured such that the inlet sides and the outlet sides from the adjacent pairs of the cores face into the same circumferential gaps; and core guide vanes disposed in the circumferential gaps, the core guide vanes have an aft portion that extends from the front end to the aft end of the heat exchanger, wherein: at the front end the heat exchanger, the core guide vanes are closer to the outlet side of the cores; and at the aft end the heat exchanger, the core guide vanes are closer to the inlet sides of the cores.
